Abstract

“Intention Cognitivism” (IC) refers to a family of theories concerning the relation between the concepts of intention and belief. While there are important differences between the various theories that belong to this family, each is committed to the idea that an agent intends to X only if they believe that they (probably) will X. In this article I argue against this core commitment of IC on the basis of recent experimental evidence concerning the ways in which ordinary speakers of English use the concepts of intention and belief. After summarizing some of this evidence, I consider a possible defense of IC, one based on the distinction between full versus partial intentions and beliefs. I report on a new study that was conducted specifically to evaluate this defense of IC, the results of which indicate that this distinction fails to protect IC against the compelling empirical evidence against it. Additionally, I consider, and argue against, two recent arguments for IC.
